Hi Experts,
Actually, I don't have much experience in UCS and I just have a request to upgrade the memory in one of the UCS servers, My company needs to purchase Cisco UCS-MR-X64G2RW to have 64GB DIMM however, the product description is saying its 64GB RDIMM DRx4 3200 (16Gb) and I got confused by what the "(16Gb)" means, can anyone help me understand what does Cisco means by 16Gb if the DIMM is size is 256 GB?
Thanks,

That is a 64GB DIMM.
The (16Gb) is referencing Rank/speed config, and could probably use a better description (64GB(16Gbx4 1H DR)

The "(16Gb)" is referencing the individual chips on the DIMM.
Think of it as a technology generation/step. A similar concept to 10Gbps vs 40Gbps network speed.

The specification defined standards for ×4, ×8 and ×16 memory devices with capacities of 2, 4, 8 and 16 Gbit.
